Forum: feature_films Subject: Q about where these films come from?

Glad to be able to see these old films.

I'm just curious how they're encoded. For instance, 'My Man Godfrey' was listed at about 5.7Gb, when I saw it, I thought that someone ripped the Criterion DVD and uploaded it. (It has about the same bitrate).

But then I downloaded it, and I looked at the frames.

Take a look at these examples:

(don't try to tell anything from the .jpg - it's there for
those who can't see a .bmp image)

Here's the BMP image (no compression)

Then take a look at the criterion screenshots:

(then scroll down to the same frame) - N.B. Please don't tell me that I have the wrong frame, it is the correct one within one or two.

With a comparable bitrate there are two immediate comparisons here:
1) It looks like this came from a TV DVR and then encoded to a high mpeg2 bitrate. This is just my guess.
2) The overscan region is VERY noticable, especially on the bottom and the right. There is a head chop on the top. (You cannot see the maid's legs or the round thing on the right).

So my question is this: Where do these come from? They look to be VHS quality at best - not a complaint - you get what you pay for. It seems that if same were 5.7G, you would have a lot higher quality. I think I could do the same in 2.5G myself. Everything on the video seems swimming.

Just like your thoughts.

Films on this section come from a variety of different sources. The films I've uploaded come from Beta SP masters, one-inch video masters or DVDs. I know that others have uploaded files from VHS sources. Granted VHS might not be the best quality, but I see this collection as a constant work in progress. If we find a better quality copy of a given film (either from a better video source or with a film that isn't so splicey or scratched or a TV print), it will be to upload it and replace the lesser quality file.

Also, in general, a higher bitrate means higher quality, but the source's quality (film quality, telecine transfer quality, video quality) will trump a high bitrate anytime.
